No, editing such game changing choices will result into crashes and game breaking moments, so no, I already told you the other solutions.
If you have 5 affection points she comes in the camp and automatically through actions you get the love confession and then you can corrupt her as much as you want.
Although it’s pretty straightforward her quest, you want her corrupted? just go full corruption till she is willing to do sex and stuff.
You want a loving relationship? Just go full affection till she agrees to come.
I always did like that without WT, it’s maybe the simplest quest in game not really a dealbreaker
